Le and his former Northcross Medical Center have agreed to pay more than $6 million to settle a related civil fraud case. U.S. Attorney Anne Tompkins says it's the largest settlement in the Western District of North Carolina against a single doctor.

Le pleaded guilty Wednesday to seven counts of health care fraud, one count of conspiracy and one count of tax evasion.

Le faces up to 10 years in prison and a $250,000 fine for the fraud charges, and five years in prison and $250,000 for tax evasion.
